The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Sony RX100 III was launched in the US market at a price of $799. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison with a 35mm slide
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
The Sony RX100 III features an one-inch sensor and has a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the Sony RX100 III among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The RX100 III indeed provides movie recording capabilities. The highest resolution format that the RX100 III can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX100 III has an electronic viewfinder with a resolution of 1440k dots. The viewfinder offers a field of view of 100% and a magnification of 0.22x. The tables below summarize some of the other core capabilities of the Sony RX100 III in connection with corresponding information for a sample of similar cameras.

One convenient feature of the RX100 III is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Cyber-shot DSC-RX100 III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX100 III offers wifi support. Wifi can be a very convenient means to transfer image data to an off-camera location.
The RX100 III has a zoom lens built in (8.8-25.7mm f/1.8-2.8), which, in full frame equivalent terms, provides a focal length range from 24 to 70mm. The camera is, hence, ready to shoot, while remaining more compact in size than an interchangeable lens camera with an optic that offers similar focal length and aperture specifications.
While the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX100 III in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).
The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
